The laser isotope analyzer research project of Chinese Academy of Sciences passed the acceptance

[China Instrument Network Instrument R&D] Recently commissioned by the Bureau of Condition Support and Finance of the Chinese Academy of Sciences, an expert from the Hefei Institute of Physical Science of the Chinese Academy of Sciences, jointly sponsored by Prof. Dong Fengzhong of the Anhui Institute of Optoelectronics and Professor Liu Guijian of the University of Science and Technology of China. The development project "Development of Isotope Analyzer Based on Wavelength Modulated Off-axis Integral Cavity Spectroscopy Technology" was accepted.

The meeting was chaired by the senior executive of the Scientific Research Condition Division of the Chinese Academy of Sciences, and was chaired by Chen Fei, director of the scientific research department of the Hefei Research Institute, and Qiu Shenji, a researcher of the Anguang Research Institute, who attended the acceptance meeting.
The test expert group reviewed the test syllabus for various technical indicators of the implementation plan, and conducted field tests on various technical indicators of the monitoring system; the acceptance expert group reviewed the relevant acceptance materials provided by the project team and heard the person in charge of the project. The work report, financial report and test report of the test team verified the operation of the equipment. After questioning and discussion, they unanimously held that the project completed the various mission objectives, assessment objectives and technical indicators specified in the implementation plan, and agreed that the project passed acceptance. .
The project has successfully developed an isotope on-line measurement system based on the wavelength-modulated off-axis integrated cavity output spectrum technology with independent intellectual property rights, which has broken through the development of online frequency-locked, long-path passive cavity resonators for laser output, and optical path adjustment, algorithm resolution, and temperature Key technologies such as precise pressure control have increased the independent innovation ability and core competitiveness of the project team in the field of laser spectroscopy. At present, the project team has developed 3 sets of prototypes in the project cycle, and conducted demonstration applications on the air environment monitoring, coal mine gas traceability, greenhouse gas emission sources and sinks, and other areas for real-time monitoring of atmospheric environmental pollutants in China. And precise analysis provides new technical means.
The acceptance expert group consists of Prof. Wang Qiuping (Chairman of the test team) and Prof. Wang Pei (Chairman of the inspection team) of the University of Science and Technology of China, Zhang Honggong of the Anhui Academy of Environmental Sciences, Professor Yu Youlong of the Hefei University of Technology, and the Wanbei Coal and Electricity Group Co., Ltd. Chen Yuping, director of the company's technical center, senior engineer, Sun Li Senior Accountant of Anhui Medical Information Institute (financial audit) and other components.
